Surface characteristics

  • Affinity tagged biomolecules have highly specific binding
  • Reduced variability in molecular orientation
  • Immobilizer surfaces improve S/N ratios
  • Streptavidin biotin interaction can be exploited to immobilize a wide range of biomolecules (proteins, peptides, haptens, nucleic acids)
Biomolecule Surface type Key features
Antibody-Binding Plates Secondary antibody Our antibody-coated plates are useful for binding assays when available antibodies are in low quantities, denatured, and become inactive upon direct adsorption to polystyrene plates.
Biotin-Binding Plates

Streptavidin

Streptavidin- and NeutrAvidin-coated plates for binding biotinylated antibodies or probes for ELISA and other target-specific assays. Biotin-binding plates are ideal for applications when direct adsorption to polystyrene denatures antibodies or the target molecule. 
GST-Binding Plates Glutathione Coated with intact glutathione (GSH) for use in capture and detection assays involving glutathione-S-transferase (GST) fusion proteins.

His Tag-Binding Plates

Nickel Chelate/Copper Chelate Nickel and copper chelate–coated plates are ideal for analyzing polyhistidine-tagged fusion proteins by ELISA-based methods.
